Acoustic Panel Coverage Estimator
https://www.theatersizing.com/calculators/acoustic-panel-coverage/
Estimate only — not a calibrated SPL meter, an acoustic report or an electrical design. Confirm with measurement.
Acoustic Panel Coverage Estimator
A common starting range is 15–25% of wall area for a living room and 20–40% for a dedicated theater. This is coverage, not a decay-time model.
Inputs
Results
- Wall area
- 47.5m²
- Target treatment
- 11.9m²
- Panel count
- 17
Calculation method
Wall area = 2(L+W)·H. Target = percent × wall area. Count = ceil(target / panel area).
Exact formula
A = 2(L+W)H. N = ceil((p/100)·A / A_panel). Limits: ignores ceiling, furniture, NRC and placement quality.
Frequently asked questions
Include the ceiling?
Not in this wall-only estimate. Add a cloud as extra area if you hang one.
NRC vs coverage?
Coverage is geometry. NRC is how well the panel works. Buy real absorbers, not egg foam.
Too dead?
Stop before 50% in a living room. Dedicated theaters can go further.
